Solution 1

Try something like this :

C#

var rept_max = (from c in nameentity.name
                where c.name == "John"
                select c).Max(c => c.amount);

var rept_min = (from c in nameentity.name
                where c.name == "John"
                select c).Min(c => c.amount);

Solution 2

Same as above.....

rept_max = (from c in nameentity.name
where c.name == "John"
select c.amount).Max();

var rept_min = (from c in nameentity.name
where c.name == "John"
select c.amount).Min();
